Some more bits for the Oliver family jigsaw puzzle for you...
While looking for something else in the transcripts of Witney St Mary marriages, I came across the following:
George Oliver, 28, bachelor, carter of Stonesfield, son of Philip Oliver, carter, married Kathleen Annie Kitchener Beale, 22, spinster [presumably of Witney, though not stated in transcript], daughter of Alfred Beale, blanket finisher, on 15 January 1921. Witnesses: Harry Howes, Elsie Margaret Beale.
William Oliver, 25, bachelor, smallholder of Stonesfield, son of Edward Oliver, publican, married Millicent Kearsey, 27, spinster [presumably of Witney, though not stated in transcript], daughter of Henry James Kearsey, smallholder, on 8 July 1922. Witnesses: Henry James Kearsey, Beatrice May Wheeler.
